Unauthenticated redirection requests with protection

ABSTRACT

A redirection object may be obtained, based on a current request of a current requestor. The redirection object request may be associated with a response to a previous request for a redirection to a destination network location, the previous request associated with a previous requestor. A current transmission origination location associated with a current requestor transmission of the current request may be determined. It may be determined whether the current transmission origination location includes a similarity to a previous transmission origination location associated with a previous transmission of the previous request, based on identification information included in the redirection object. It may be determined whether to initiate a redirect operation of the current requestor to the destination network location, based on a result of the determining of the similarity between the current transmission origination location and the previous transmission origination location.

BACKGROUND

Users of electronic devices are increasingly relying on information obtained from the Internet as sources of news reports, ratings, descriptions of items, announcements, event information, and other various types of information that may be of interest to the users. Further, users are increasingly relying on web sites to shop for products and services online. The websites users visit may redirect users to other websites for various reasons. For example, a mobile device application may not provide support for a particular web site rendering technique (e.g., MICROSOFT SILVERLIGHT technology), and the application may thus wish to have some web sites rendered by another application instead. Thus, a first application may provide to a second application the Uniform Resource Locator (URL) of a website so that it may be rendered. Web-browsing sessions may maintain state about a user via technology such as browser cookies, which are isolated to a single application. In order for the user's browsing session in the first application to continue in the second, some browser cookies may be transferred to the second application. To accomplish this, the first application may provide the second application with a URL to a website that issues the appropriate cookies and then redirects to the original URL. To facilitate this, a website may expose a service whereby an application may request such a redirect URL. However, phishing users may use redirect URLs to redirect other users to web sites that may not be desired by the other users.

SUMMARY

According to one general aspect, a system may include a redirect request receiving component that obtains a first request from a first originating requestor for a redirection Uniform Resource Locator (URL). The system may also include a first originating location determination component that determines a first originating Internet Protocol (IP) address associated with an originating transmission of the first request. The system may also include a redirection object generator that generates, via a device processor, a first redirection object that includes a retransmission location indicator and first information associated with identification of the first originating IP address. The system may also include a redirection object receiving component that obtains the first redirection object transmitted from a second originating requestor. The system may also include a second originating location determination component that determines a second originating IP address associated with an originating transmission of the first redirection object from the second originating requestor. The system may also include a similarity determination component that determines an originating transmission location similarity between the first originating IP address and the second originating IP address. The system may also include a redirect decision component that determines whether to initiate a redirection associated with the first redirection object, based on the determined originating transmission location similarity.

According to another aspect, a redirection object may be obtained, based on a current request of a current requestor. The redirection object may be associated with a response to a previous request for a redirection to a destination network location, the previous request associated with a previous requestor. A current transmission origination location associated with a current requestor transmission of the current request may be determined. It may be determined whether the current transmission origination location includes a similarity to a previous transmission origination location associated with a previous transmission of the previous request, based on identification information included in the redirection object. It may be determined whether to initiate a redirect operation of the current requestor to the destination network location, based on a result of the determining of the similarity between the current transmission origination location and the previous transmission origination location.

According to another aspect, a computer program product tangibly embodied on a computer-readable storage medium may include executable code that may cause at least one data processing apparatus to receive, based on a current request, a redirection object, the redirection object associated with a response to a previous request for a redirection to a destination network location. Further, the at least one data processing apparatus may determine a current transmission origination location associated with the current request. Further, the at least one data processing apparatus may determine whether the current transmission origination location includes a similarity to a previous transmission origination location associated with a previous transmission of the previous request, based on identification information included in the redirection object. Further, the at least one data processing apparatus may determine whether to initiate a redirect operation, based on a result of the determining of the similarity.

DETAILED DESCRIPTION

Application developers may desire redirect Uniform Resource Locators (URLs) to be generated on a server at run-time. While this may be accomplished by authenticating a client associated with a user, an authentication may involve submission of a secret known by the client and the server. For many applications, this may not be feasible because of the deployment model of the application. However, use of an unauthenticated service to generate redirect URLs may expose the service to phishing attacks, as a phishing user may create URLs such as “www.goodcompany.com/redirect?url=www.myphishingsite.com”, and an unsuspecting other user may trust the URL because of the domain name “goodcompany.com”.

Example techniques discussed herein may provide service-generated redirect URLs for unauthenticated client applications that may reduce the risk of phishing attacks.

According to example embodiments, a service may generate short-lived, and/or one-time-use redirect URLs, without client authentication, which may be validated based on a comparison of originating locations of the request for the redirect URL and the request to be redirected based on a transmission of the generated redirect URL. If the originating locations of the two requests do not match, or are not otherwise determined to be similar, then the request for redirection may be declined, and an error message may be sent to the requestor.

According to an example embodiment, the service may generate the redirect URL and may store it (e.g., in a list) using a redirect URL identifier. The redirect URL may be associated with, or may include, an originating transmission location associated with the client requesting the redirect URL. For example, the originating transmission location may include an Internet Protocol (IP) address from which the client transmits the request for the redirect URL to be generated by the service. According to an example embodiment, the service may then send a redirect request to the requesting client, the redirect request including a retransmission URL (e.g., a URL for transmission of the request to redirect the client) and an indication of the redirect URL identifier. When the service receives the redirect request, the service may then retrieve the redirect URL, based on the redirect URL identifier, and may compare the originating transmission location associated with the client requesting the redirect URL that is stored with the redirect URL, with an originating transmission location associated with the transmission to the service, of the redirect request. If the two originating transmission locations do not match, or are not determined to be similar, the service may decline the redirect request. Thus, if a phishing user obtains a redirect request from the service, then the redirection may not be performed if the redirect request is transmitted from another user.

According to an example embodiment, the service may perform the redirection if a match (or similarity) is determined, and the redirect URL may be removed from storage.

If there is no redirect URL associated with the redirect URL identifier, then the redirect URL may have expired, or may have not existed.

According to an example embodiment, the service may remove redirect URLs older than a predetermined age, for example, in a background process.

According to an example embodiment, the service may include information in the redirect request that identifies the originating transmission location associated with the client requesting the redirect URL, in lieu of storing the redirect request. According to an example embodiment, the originating transmission location associated with the client requesting the redirect URL may be encoded (or encrypted), and placed in a predetermined arrangement in the redirect request. The requested URL for which the client requests redirection may also be encoded in the redirect request. According to an example embodiment, the service may decode the redirect request after receiving it from a requestor, and may determine whether the two originating transmission locations match, or are similar, as discussed above.

As further discussed herein, FIG. 1 is a block diagram of a system 100 for protected redirection requests. As shown in FIG. 1, a system 100 may include a protected redirection request manager 102 that includes a redirect request receiving component 104 that may obtain a first request 106 from a first originating requestor 108 for a redirection Uniform Resource Locator (URL). For example, the first request 106 may include a request for a redirection URL to a web site that is of interest to the first originating requestor 108.

According to an example embodiment, the protected redirection request manager 102 may include executable instructions that may be stored on a computer-readable storage medium, as discussed below. According to an example embodiment, the computer-readable storage medium may include any number of storage devices, and any number of storage media types, including distributed devices.

For example, an entity repository 110 may include one or more databases, and may be accessed via a database interface component 112. One skilled in the art of data processing will appreciate that there are many techniques for storing repository information discussed herein, such as various types of database configurations (e.g., SQL SERVERS) and non-database configurations.

According to an example embodiment, the protected redirection request manager 102 may include a memory 114 that may store the first request 106. In this context, a “memory” may include a single memory device or multiple memory devices configured to store data and/or instructions. Further, the memory 114 may span multiple distributed storage devices.

According to an example embodiment, a user interface component 116 may manage communications between a user 118 and the protected redirection request manager 102. The user 118 may be associated with a receiving device 120 that may be associated with a display 122 and other input/output devices. For example, the display 122 may be configured to communicate with the receiving device 120, via internal device bus communications, or via at least one network connection.

According to an example embodiment, the protected redirection request manager 102 may include a network communication component 124 that may manage network communication between the protected redirection request manager 102 and other entities that may communicate with the protected redirection request manager 102 via at least one network 126. For example, the at least one network 126 may include at least one of the Internet, at least one wireless network, or at least one wired network. For example, the at least one network 126 may include a cellular network, a radio network, or any type of network that may support transmission of data for the protected redirection request manager 102. For example, the network communication component 124 may manage network communications between the protected redirection request manager 102 and the receiving device 120. For example, the network communication component 124 may manage network communication between the user interface component 116 and the receiving device 120.

A first originating location determination component 128 may determine a first originating Internet Protocol (IP) address 130 associated with an originating transmission of the first request 106.

A redirection object generator 132 may generate, via a device processor 134, a first redirection object 136 that includes a retransmission location indicator 138 and first information 140 associated with identification of the first originating IP address 130.

In this context, a “processor” may include a single processor or multiple processors configured to process instructions associated with a processing system. A processor may thus include multiple processors processing instructions in parallel and/or in a distributed manner. Although the device processor 134 is depicted as external to the protected redirection request manager 102 in FIG. 1, one skilled in the art of data processing will appreciate that the device processor 134 may be implemented as a single component, and/or as distributed units which may be located internally or externally to the protected redirection request manager 102, and/or any of its elements.

A redirection object receiving component 142 may obtain the first redirection object 136 transmitted from a second originating requestor 144.

A second originating location determination component 146 may determine a second originating IP address 148 associated with an originating transmission of the first redirection object 136 from the second originating requestor 144. According to example embodiments, the first originating location determination component 128 and the second originating location determination component 146 may be the same component, or may both be included in an originating location determination component 150. According to example embodiments, the first originating location determination component 128 and the second originating location determination component 146 may be located on separate devices.

A similarity determination component 152 may determine an originating transmission location similarity 154 between the first originating IP address 130 and the second originating IP address 148. For example, the originating transmission location similarity 154 may be based on equality, or a geographic proximity of a host of the first originating IP address 130 to a host of the second originating IP address 148.

A redirect decision component 156 may determine whether to initiate a redirection associated with the first redirection object 136, based on the determined originating transmission location similarity 154. For example, if the similarity determination component 152 determines that the first originating IP address 130 and the second originating IP address 148 are equal (or similar), then the redirect decision component 156 determine that a redirection will be initiated.

According to an example embodiment, the first request 106 may include a request URL associated with a destination network location requested for redirection of a requesting client associated with the first originating requestor 108, the requesting client associated with the originating transmission of the first request 106 from the first originating IP address 130.

According to an example embodiment, the second originating requestor 144 may include the first originating requestor 108.

According to an example embodiment, the similarity determination component 152 may determine the originating transmission location similarity 154 between the first originating IP address 130 and the second originating IP address 148 based on one or more of determining that the first originating IP address 130 and the second originating IP address 148 are equal, determining that the second originating IP address 148 is hosted within a predetermined geographic radius of a hosting of the first originating IP address 130, or determining that the first originating IP address 130 and the second originating IP address 148 share a common client ownership associated with the first originating requestor 108 and the second originating requestor 144. For example, if the first originating IP address 130 and the second originating IP address 148 are both owned by a major, trustworthy corporation for business use by its in-house employees, then a similarity may be determined.
